Which Chevrolet car used the nickname “Kammback” for its unusual rear design?

The Chevrolet Vega used the nickname “Kammback” for its unusual rear design.

Chevrolet offered a Vega Kammback station wagon beginning in 1971. Its name referred to the Kammback aerodynamic principle, in which a vehicle’s rear is abruptly truncated rather than smoothly tapered to a point. The design aimed to reduce aerodynamic drag while preserving useful cargo space.

The Kammback was one of several Vega body styles, alongside the notchback sedan, hatchback coupe, and later wagon variants. It was a compact utility model rather than a conventional full-size station wagon.

The name is sometimes confused with “Kamm tail,” a broader aerodynamic term used by many manufacturers. In Chevrolet’s lineup, Kammback specifically identified the Vega wagon body style, not a separate engine or trim level.
